Colin Kaepernick has filed an application to trademark a black-and-white image of his face and hair, according to U.S. Patent and Trademark Office records.

The former San Francisco 49ers quarterback, who was the first NFL player to kneel during the national anthem as a means of protesting racial inequality and police brutality, applied for the trademark through a company that he owns, Inked Flash Inc., on Friday.

Kaepernick played for the Nevada Wolf Pack from 2006 to 2010. In the most memorable game in Pack history, he led Nevada to a 34-31 OT win over Boise State in 2010. Nevada finished that year 11th in the nation.

According to the application, Kaepernick is considering using the mark on a wide variety of items, from candles and shampoo bottles to clothes, mugs and backpacks. He may also use the mark in conjunction with "providing classes, workshops, seminars and camps in the field of self empowerment and awareness to properly interact with law enforcement" and the "production of television shows and films," according to USPTO records.

Kaepernick, who remains a free agent and has filed a collusion grievance against NFL owners, also sought to previously trademark "I'm With Kap" for use on clothing. That application was filed in August.
